Improved metallic cask



UNITED STATES PATENT OEEIcE.

VILLIAM B. SCAIFE, OF PITTSBURG, PENNSYLVANIA.-

vIIVIPROVED METALLIC CASK.

Specification forming part of Letters Patent No. 528,014, dated April 24, 1864).

To all whom t may concern,.-

Be it known that I, IVILLIAM B. Sonnen,

i declare that the following is a full, clear, and

exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a longitudinal section of a cask constructed according to my invention. Fig. 2 is a transverse section of the same.

Similar letters of reference indicate corresponding parts in both figures.

My invention' consists in a novel construction of sheet-iron casks, barrels, or kegs, for coal-oil or other substances, whereby I am enabled to combine facility of construction with extreme lightness and strength in the form most desirable for transportation.

To enable others skilledin the art to make and use my invention, I will proceed to describe itin detail, with reference to the accompanying drawings. u

The sides are made with longitudinal corrugations, as indicated by a a in both figures of the drawings; but as it would be very difficult, if not impossible, to attach the heads secu rely if these corrugations extended the whole length, I make them of gradually-diminishing depth in each direction from the middle ofthe length of the cask, so that they vanish into a plain part, b b, which is left at each end for the purpose of forming lap-joints e f with heads c d. The lap-joints may be of either of the forms represented in Fig. 1, where a different kind of joint is shown at each end, or of any other construction in which the lap is made to project longitudinally beyond the heads in a manner corresponding with the anneau 2, but must be plain near their edges to enable the joints with the sides to be formed with facility. rIhe sides may be composed of as many sheets as may be requisite, united by lap-seams running lengthwise of the cask and closed by soldering. One of the heads is' fitted with a screw-bung, h, which is to be removed and replaced by a cock when the contents of the cask are to be drawn off.

By the longitudinal corrugation of the sides of the cask great strength is obtained with comparatively light plates, and by the peculiar form of the corrugations the bilge is obtained which enables the cask to be rolled labout with facility, and facility is obtained for making lap-joints with the heads,while by the extension ofthe lap-joints beyond the heads `in the form of the chine of a wooden cask, the necessary convenience is afforded for handling it.

I do not claim the making of casks, barl rels, or kegs of corrugated metal in any other manner than that herein specified; but

I claim as my invention- As a new article of manufacture, a Cask, barrel, or keg made of sheet-iron having its sides corrugated longitudinally in the manner described, to produce a bilge and leave the parts near the heads plain, and united with t-he heads by lap-joints, which extend beyond the heads in the form of a chine, as herein dcscribed.
